3. The choice of hose pump hose The key component of the hose pump is the tube, which is the only through part of the pump. Only the hose to meet the technical requirements, the pump can work properly, it should be based on the purpose of use and the nature of the media to choose. Common pipe grades are: Tygon (R3603, ordinary type): inexpensive, corrosion-resistant, generally used in laboratories, can be used for good vacuum pump system; Tygon (special type): transport of hydrocarbon medium, the most suitable In gasoline, fuel oil and lubricants; Viton: can deliver special corrosive chemicals and reagents, but expensive, short service life; Silicone: meet the UADA (rubber formula test solvent) standards and the FDA (rubber formula test solvent) Wide operating temperature range, the temperature generated by the hardening of small, affordable, long life, when the pump head speed of 200r / min, 450h after work, there is still some flexibility. The choice of pipe, the main consideration of the following factors: corrosion resistance, operating conditions (pressure, temperature, flow, etc.), with or without toxicity and price. These conditions affect each other, so we should make a comprehensive trade-off before we can make economic choices. Due to the long service life of Silicone, the working time of the continuous operation of the pump head is up to 1200h when the rotating speed of the pump head is 50r / min, good elasticity, high chemical stability, non-toxic, inexpensive and adequate supply, widely used. 4. Hose pump application and effect Hefei Quartet Phosphate Fertilizer Co., Ltd. (formerly Anhui Jianghuai phosphate rock) originally used to transport pulp is four sets of diaphragm pumps, the transmission distance of 30m, fall Qiao m (2 parallel use, and the other 2 Taiwan relay delivery). Now after the process of transformation, use a hose diameter of 65mm hose instead of the original diaphragm pump, before and after the transformation process shown in Figure 2, Figure 3. Click here to see all news pictures Hose pump less investment, long service and maintenance cycle, less maintenance costs, operating costs decline. 5. Conclusion In the early 1980s, with the rapid development of the rubber-plastic industry, flexible and corrosion-resistant new materials and new varieties of pipes continued to emerge, a large number of hose pumps emerged, their varieties and products close to the same type of pump Of 1/3. Hose pump has been applied to the laboratory quantitative fluid delivery, chemical spray granulation plant, thick slurry, concentrated pulp, saturated brine delivery, sewage treatment plant sludge transport and other fields, especially in recent years in the complex phosphorus Application of fertilizer production has been made more obvious economic benefits, it is worth promoting.
